I am, too, having severe dropout issues with UR44 and Windows 11.
I am using a Dell Precision 774 i9. Especially if there’s some CPU load on the system the drop outs are significant. I am using the laptop for heavy java dev work (IntelliJ, docker). I cannot even use the UR44 interface for Teams/Zoom/GoogleMeet calls while I have my dev environment up and running, because the drop outs are unbearable.
If there’s no load on the system, the drop outs are (almost) disappearing.
Having said the above, I was using the same environment on windows 10 (!!!) WITH ABSOLUTELY NO AUDIO PROBLEMS whatsoever - No dropouts, nothing - even under significant system load, I was still able to watch a BluRay video … !!!
So apparently, it seams to be Win 11 specific for me.
I tried to mitigate the problem by installing the previous version of ASIO driver (v2.0.4) as suggested by a support article - no luck.
The (hidden) Error Info in the Yamaha Steinberg USB Driver GUI shows that the USB communication (RECOV) is being reset every few seconds (aka drop outs) and USBTS errors piling up, hence, rendering audio unusable.
I was further investigating the issue using LatencyMon tool. It revealed that the ACPI.sys driver is on the top of the list of “bad” drivers with highest ISRcount/HighersExec/TotalExec values.
Yes, I know, you might say that there could not be stable audio if there’s high load on the system. However, again, everything was working GREAT on windows 10!!! And yes, I also tried very conservative ASIO buffer sizes… I am currently not using my UR44 for any audio production, just for work, watching videos and listing to music…
I am about to downgrade to Win 10, but before I do that, I am just wondering if anyone else had similar issue with Window 11, especially on a Dell Laptop.
Thanks for any feedback!
